Nginx 上的 Django 需要帮助

Question

我正在尝试将我的网站部署到 aws ec2。它在 python/django 中，我想学习如何自己部署网站。我对 aws 的 EBS 有一些问题，所以首先我想知道如何手动完成。 我决定为此使用 gunicorn 和 nginx。

我可以在虚拟环境中使用 gunicorn 运行网站，并在 /home/ec2-user/gunicorn_start.bash 中创建了以下脚本：

#!/bin/bash

NAME="davidbiencom"                                  # Name of the 
application
DJANGODIR=/home/ec2-user/davidbien             # Django project directory
SOCKFILE=/home/ec2-user/virtual/run/gunicorn.sock
USER=ec2-user                                     
GROUP=ec2-user                                    
NUM_WORKERS=3                                     
DJANGO_SETTINGS_MODULE=davidbiencom.settings             
DJANGO_WSGI_MODULE=davidbiencom.wsgi                     

echo "Starting $NAME as `whoami`"

# Activate the virtual environment
cd $DJANGODIR
source /home/ec2-user/virtual/bin/activate
export DJANGO_SETTINGS_MODULE=$DJANGO_SETTINGS_MODULE
export PYTHONPATH=$DJANGODIR:$PYTHONPATH
# Create the run directory if it doesn't exist
RUNDIR=$(dirname $SOCKFILE)
test -d $RUNDIR || mkdir -p $RUNDIR

# Start your Django Unicorn
# Programs meant to be run under supervisor should not daemonize themselves (do$
exec gunicorn ${DJANGO_WSGI_MODULE}:application \
--name $NAME \
--workers $NUM_WORKERS \
--user=$USER --group=$GROUP \
--bind=unix:$SOCKFILE \
--log-level=debug \
--log-file=-

我相信这运行良好，因为没有错误。 接下来我安装 nginx 并启动服务。当我得到欢迎页面时，我确认它正在运行。接下来我执行以下操作：

1. 转到 /etc/nginx/nginx.conf 并将以下内容添加到 http

   包括/etc/nginx/sites-enabled/*.conf；

然后我在 /etc/nginx/sites-available 和 sites-enabled 中创建两个文件夹。 我创建一个文件 davidbien.conf 并在里面输入以下内容（更新）：

upstream app_server {
# fail_timeout=0 means we always retry an upstream even if it failed
# to return a good HTTP response

# for UNIX domain socket setups
server unix:/home/ec2-user/virtual/run/gunicorn.sock fail_timeout=0;

# for a TCP configuration
# server 192.168.0.7:8000 fail_timeout=0;
}

server {
listen 80;
server_name 35.176.185.50;

#Max upload size
client_max_body_size 75M;   # adjust to taste

location /static/ {
    root /home/ec2-user/davidbien/static;
}

location / {
  # checks for static file, if not found proxy to app
  try_files $uri @proxy_to_app;
}

location @proxy_to_app {
  proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
  # enable this if and only if you use HTTPS
  # proxy_set_header X-Forwarded-Proto https;
  proxy_set_header Host $http_host;
  # we don't want nginx trying to do something clever with
  # redirects, we set the Host: header above already.
  proxy_redirect off;
  proxy_pass http://app_server;
  }
}

我保存此文件并运行以下命令：

ln -s /etc/nginx/sites-available/davidbiencom.conf /etc/nginx/sites-enabled/davidbiencom.conf

完成此操作后，我重新启动 nginx，当我输入 IP 地址时，我收到 502 bad gateway 错误。

这里可能有什么问题？ 谢谢。

编辑： 这是来自 var/log/nginx/error.log 的错误日志

Answer 1

您告诉 nginx 它必须将请求转发到 127.0.0.1:3031，但是从我从脚本中看到的启动 gunicorn 的内容来看，如果您要在 127.0.0 上启动 gunicorn 工作者，gunicorn 会绑定到一个套接字。 0.1:3031 它应该可以工作
